I didn't say it would happen "any time soon", or even at all. I said IF IT BECOMES A THING. I read a wide range of projections on when it may occur, so I don't know.
And I do fully expect automated food prep in due time for many menu items. I think cost is the only barrier today. And by extension, we could reach a time when there are zero "unskilled" jobs for folks, though that is pretty far off I think.
